Self-cleaning, anti-glare windows inspired by moth eyes

A revolutionary new type of smart window developed by University College London (UCL) and the Engineering and Physical Sciences Research Council (EPSRC) could cut window-cleaning costs in tall buildings while reducing heating bills and boosting worker productivity. Partially inspired by the reflective properties of moth eyes, this smart window is said to be self-cleaning, energy-saving, and anti-glare.

Speedy single-molecule nanosubs powered by UV light

For some time now, we've been hearing about the attempts by various groups to develop so-called nanosubmarines. Among other things, these microscopic "molecular machines" could conceivably be used for applications such as targeted drug delivery within the human body. Recently, scientists at Houston's Rice University created nanosubs that move at a "breakneck pace" when exposed to ultraviolet light.

World's first "porous liquid" could be used for CO2 sequestration

The Italians have a colorful expression – to make a hole in water – to describe an effort with no hope of succeeding. Researchers at Queen's University Belfast (QUB), however, have seemingly managed the impossible, creating a class of liquids that feature permanent holes at the molecular level. The properties of the new materials are still largely unknown, but what has been gleaned so far suggests they could be used for more convenient carbon capturing or as a molecular sieve to quickly separate different gases.

Nanoscale wrench is just 1.7 nanometers wide

Envision a nanoscale wrench, capable of controlling shapes at the nanoscale level to create customized molecules. That's what Severin Schneebeli, a University of Vermont chemist and his team have developed. The opening on this mini wrench is only 1.7 nanometers, roughly a hundred-thousand-times smaller than the width of human hair.
